I like this part: "As far as java.util.Calendar goes, I'm sure it has a purpose, but since we've been on the Gregorian now for several friggin' centuries (and with no sign of imminent change), I think we'd be safe having Calendar be one of those classes that is neither seen nor heard except in the 0.000001% chance that you actually need to do something with the scrolls of dead monks."
